Suppose that N = sqrt of x (only x) + 3 (not under sqrt sign) models the number of cases of an infection, in millions, of a disease x years from now.
\n" ); document.write( ":
\n" ); document.write( "\"N+=+sqrt%28x%29+%2B+3\"
\n" ); document.write( ":
\n" ); document.write( "a) approximately how many cases of the infection will there be 9 yrs from now?
\n" ); document.write( "\"N+=+sqrt%289%29+%2B+3\"
\n" ); document.write( "N = 3 + 3
\n" ); document.write( "N = 6 million cases
\n" ); document.write( ":
\n" ); document.write( "b) In how many years will there be 5 million cases?
\n" ); document.write( "\"sqrt%28x%29+%2B+3+=+5\";
\n" ); document.write( "\"sqrt%28x%29+=+5+-+3\"
\n" ); document.write( "\"sqrt%28x%29+=+2\"
\n" ); document.write( "Square both sides:
\n" ); document.write( "x = 4 years
\n" ); document.write( "
\n" ); document.write( "
\n" );
